Failed Importing Cyrillic (UTF8) json file into MongoDB database - mongodb

Question

Question: How to use mongoimport.exe utility to import UTF8 json documents with Cyrillic chars into mongodb database under MS Windows 10? (mongoimport.exe online docs do not provide any information or I'm missing it?)
Environment: MS Windows 10, MongoDB 3.2.3, mongoimport.exe
Source UTF8 json file:
{
"PersonnelNumber": "15128",
"OrderNumber": "765-01",
"OrderDate": "2011-05-04T00:00:00",
"JobPosition": "Слесарь по ремонту подвижного состава"
}
Command line:
"C:\Program Files\MongoDB\Server\3.2\bin\mongoimport.exe" --db testOrders --collection orders --drop < "TestOrder.json"
Import log:
2016-03-01T14:47:04.350+0300 connected to: localhost
dropping: testOrders.orders
Failed: error processing document #1: invalid character 'ï' looking for beginning of value
imported 0 documents
Note
ANSI version of the test file is getting imported without errors but Cyrillic char codes are stored in mongoDb database incorrectly, here is how they are displayed in mongoDb shell:
MongoDB shell version: 3.2.3
connecting to: testOrders
> db.orders.findOne()
{
"_id" : ObjectId("56d5838aef35e4f7c03e81bd"),
"PersonnelNumber" : "15128",
"OrderNumber" : "765-01",
"OrderDate" : "2011-05-04T00:00:00",
"JobPosition" : "������� �� ������� ���������� �������"
}

Here is a screenshot with hex codes of UTF8 and ANSI files:
When using C# driver (VS2015) to list imported by mongoimport.exe utility json file
foreach (var order in
(new MongoClient()).GetDatabase("testOrders")
.GetCollection<BsonDocument>("orders").FindSync(new BsonDocument()).ToList())
System.Console.WriteLine("{0}", order.ToString());
the test output also has wrong Cyrillic chars:
{
"_id" : ObjectId("56d5838aef35e4f7c03e81bd"),
"PersonnelNumber" : "15128",
"OrderNumber" : "765-01",
"OrderDate" : "2011-05-04T00:00:00",
"JobPosition" : "������� �� ������� ���������� �������"
}
When using C# driver (VS2015) to insert BsonDocument from C# and then to list imported by mongoimport.exe utility json file/document and the BsonDocument document inserted via C# code
var collection = (new MongoClient()).GetDatabase("testOrders")
.GetCollection<BsonDocument>("orders");
var document = new BsonDocument
{
{"PersonnelNumber", "15128" },
{"OrderNumber", "765-01"},
{"OrderDate", "2011-05-04T00:00:00"},
{"JobPosition", "Слесарь по ремонту подвижного состава"}
};
collection.InsertOne(document);
foreach (var order in collection.FindSync(new BsonDocument()).ToList())
System.Console.WriteLine("{0}", order.ToString());
the former has incorrect Cyrillic chars and the latter has correct Cyrillic chars:
{
"_id" : ObjectId("56d5838aef35e4f7c03e81bd"),
"PersonnelNumber" : "15128",
"OrderNumber" : "765-01",
"OrderDate" : "2011-05-04T00:00:00",
"JobPosition" : "������� �� ������� ���������� �������"
}
{
"_id" : ObjectId("56d58c5c1ed24820b80b80f6"),
"PersonnelNumber" : "15128",
"OrderNumber" : "765-01",
"OrderDate" : "2011-05-04T00:00:00",
"JobPosition" : "Слесарь по ремонту подвижного состава"
}
